Complex formation of Al2(SO4)3 in water-formamide mixtures

Abstract

The kinetics of formation of AlSO 4 + has been investigated in mixtures of water and formamide. In contrast to similar measurements with BeSO4, the substitution of solvating formamide molecules by the sulfate ion cannot be observed on the aluminum cation. On the other hand, with Al3+ cations three well separated water substitution processes are observed, as compared to a single one only with Be2+. An explanation for this behavior and for the different pH dependence of the sulfate complex formation for Al3+ and Be2+ cations is suggested.
